'PHOTOGRAPHIC CAMERA.

SPECIFICATION forming part of Letters Patent No. 698,901, dated April 29, 190.2.

Application filed July 25, 1900.

To all whom it may concern.-

Be it known that I, FRANK A. BROWNELL, of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Photographic Cameras; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the reference-numerals marked thereon.

My present invention relates to photographic cameras, and particularly to that class adapted to be folded compactly and capable of being carried in the pocket, if desired; and it consists in certainimprovements in construction and combinations of parts whereby the camera may be supported so that exposures may be readily made with the camera either in vertical or horizontal posi-' tion.

The invention further consists in improved constructions which simplify and cheapen the device, all as will be hereinafter fully de-' scribed, the novel features being pointed out in the claims at the end of this specification.

In the drawings, Figure 1 is a perspective view of my camera in vertical position ready for making an exposure; Fig. 2, a front elevation of the camera when located on its side; Fig. 3, a vertical longitudinalsectional view with the parts in the position shown in Fig. 1; Fig. 4E, avertical transverse sectional view of the upper end.

Similar reference-numerals indicate similar parts.

The main casing of the camera is provided with the film-chambers land 2 at top and bottom'and a central chamber or recess 3, located between them, open at the front and provided in the lower side with a way or track plate 4, on which the lens-support or camera-front 5 is supported when the camera is folded. At the rear of the chamber 3-is the aperture 6, through which the film is exposed to the lightrays passing through the lens 7, located in the support 5. The rear end of the folding bellows 8 is secured around the aperture 6,

its upper end extending slightly beyond the casing, and the centering device cooperating with this stud is the winding-key 12, having an operating-handle 13, journaled in a plate 14, also having a loop 15, similar to the loop 11, and to these

loops

11 and 15 is attached a carrying-handle 16, as shown in Figs. 1 and 4. At the rear of the casing is a removable cover-plate 17, between which and the rear of the bellows the film and the black paper of a film cartridge extend in passing from the lower to the upper film-chamber, rollers 18 being arranged at the edges of the film-chambers, as usual.

20 indicates a door, preferably constructed of sheet metal, hinged at 21 to the lower edge of the chamber 3 and adapted to close the latter, with the bellows and lens support inclosed, said door being supported'when open by the links 22 hinged thereto and provided with longitudinal slots 23, having the recesses 24 at the upper ends, and also with springs 25, the free ends of which are opposite the recesses.

26 indicates pins secured at the sides of the chamber 3, extending through the slots in the links and engaging in the recesses 24 when the front door is opened, the springs throwing the links upwardly to'cause this engagement automatically,-'as will be understood. The end of the door is provided with acatchrecess 27 in the track-plate 35, cooperating when the door is closed with a hooked catch 28 in the chamber 3, released bya button 29, accessible from the exterior of the casing, and when the catch is released the door is automatically opened by a coiled spring 30 in the chamber 3 and having a free end 31, operating upon a projection 32 on the door. Upon the inner face of the door is a way or track plate 35, which is in line with the way or track 4 when the door is open and, supporting the lens support or front 5, is adapted to slide upon the way thus formed.

The lensfront 5 is supported upon a bracket or slide having fastening devices, such as shown in Patent No. 684,349, the application for which was a division of this application.

WVhen the camera is used to make a time exposure,it may be secured to a tripod, the securing-screw of which may enter the threaded thimble 50in the side piece; but as tripods are not usuallyemployed in connection with handcameras of this general description it is desirable to provide means for holding the camera steady, and as the lens-support is arranged centrally of the casing and is not Wide or high enough to rest upon a table or other support I provide extensible supports upon the hinged door, which will effectually support the front end of the camera when extended. The outer side of the door is provided with a recess, in which is arranged a supporting-leg 54, pivoted at 55 and having at its inner end an angular portion, with which cooperates a flat spring 56,adapted to hold the leg folded within the recess and substantially flush with the surface of the door or extended, as shown in Fig. 1, said leg being of such length that the camera-casing may rest upon its lower end and the leg and be held steady.

57 indicates a supporting rod or leg movable in a guide 58 transversely of the door andinaplane parallel therewith and adapted to be extended so that its lower end will ongage a table or support when the camera is located on its side, as in Fig. 2, said leg being provided with notches 59, with which engages a spring 60 to hold the leg in adjusted position, though permitting it to be moved in or out, as may be desired, for the purposes of adjustment.

Mounted upon the top of the lens-support is a finder (51, such as shown in Patent No. 684,347, the application for which was filed as a division of this application.

The camera and its attachments as a whole are simple, and the parts being made of sheet metal are durable and easily formed and assembled by unskilled operators.

I claim as my invention- 1. In a camera, the combination with the casing having film-chambers at opposite ends, and a central chamber between them, having the way at the bottom, of a door for closing the central chamber and hinged near one of the film-chambers, and on a center parallel with the axis thereof and the hinged supporting-leg upon the outer side of the door.
